C Compare String: strcmp()

The strcmp(first_string, second_string) function compares two string and returns 0 if both strings are equal.

Here, we are using gets() function which reads string from the console.

#include<stdio.h>
#include <string.h>
int main(){
char str1[20],str2[20];
printf("Enter 1st string: ");
gets(str1);//reads string from console
printf("Enter 2nd string: ");
gets(str2);
if(strcmp(str1,str2)==0)
printf("Strings are equal");
else
printf("Strings are not equal");
return 0;
}

 

Output:

Enter 1st string: hello 

Enter 2nd string: hello 

Strings are equal
